Scientists developing remote-control cyborg moths

We've been hearing a lot about the development of tiny flying sensor-equipped robots, that could be sent into areas such as disaster sites to seek out survivors or survey the damage. However, why go to the trouble of designing those robots from scratch, when there are already ready-made insects that are about the right size? That's the thinking behind research being conducted at North Carolina State University, which is aimed at converting moths into "biobots." Read More

Paint-on "sensing skin" is designed to detect damage in concrete structures

Although concrete structures such as bridges are now often built with strain sensors embedded within them, that certainly hasn't always been the case. In order to alert authorities to cracks developing within these older structures, one solution involves attaching sensors to them. Researchers from North Carolina State University and the University of Eastern Finland are working on an alternative, however – an electrically-conductive paint-on "sensing skin." Read More

Bamboo inspires new process for making metals tougher

Steel is a common benchmark against which the strength of materials is measured, with "stronger than steel" a familiar catch cry for those touting the properties of some new space-age material. But now researchers at North Carolina State University have created steel that is stronger than steel using a process that increases the toughness of various metals by altering the microstructures within them.Read More

NFL may track footballs using magnetic fields

Have you ever wondered how game officials know if the football has passed the goal line, in situations where it's hidden under a pile-up of players? Well, sometimes they don't know, and they just have to hope that it isn't moved as the players get up. A team of researchers from North Carolina State University, Carnegie Mellon University and Disney Research, however, may have a solution. They're developing a method of tracking a football via low-frequency magnetic fields. Read More

Ultrasound device could help detect cause of heart attack and stroke

While existing ultrasound technologies are able to identify plaque buildup on artery walls, determining when that plaque is at risk of breaking off, resulting in a heart attack or stroke, has proven a more complicated task. A team of researchers from North Carolina State University has now developed a dual-frequency ultrasound device that could help identify so-called vulnerable plaque and enable a more accurate diagnosis for at-risk patients.

"Smart bomb" puts antibiotic resistant bacteria in its sights

The increasing prevalence of bacteria resistant to antibiotic drugs is largely blamed on the over prescription and use of such drugs in humans and animals, leading to the evolution of so-called "superbugs." A new antibiotic "smart bomb" that can target specific strains of bacteria could provide the next-generation antibiotic drugs needed to stave off the threat of antibiotic-resistant bacteria.Read More

Two-in-one nanoparticles exploit tumor cells to precisely deliver multiple drugs

A common strategy for treating tumors is combining two or more drugs, which has the effect of decreasing toxicity and increasing the synergistic effects between the drugs. However, the efficacy of this kind of cocktail treatment suffers when the drugs require access to different parts of the cell, a bit like fighting a battle by depositing all your archers on the same spot as your infantrymen. By making use of nanoparticle-based carriers, researchers at North Carolina State University are able to transport multiple drugs into cancerous cells optimally and precisely, in maneuvers that any field commander would be proud of.

Phase-change mug is claimed to keep coffee hot (but not TOO hot) for hours

Drinking hot beverages can be a tricky business. If you don't want them becoming tepid too quickly, you have to pour them into your mug while they're still too hot. Even then, you're left with a relatively short period in which they're "just right." The designers of the Temperfect mug, however, want to change that. They claim that their mug can keep your drink at the perfect sipping temperature for hours at a time, without using any electricity. Read More
